See Without Glasses

Hand fist hole to see without glasses

The science behind this trick is simple. The hand fist limits the light to the eyeball and increase focus i.e. the light is coming through from one place and one direction only which is why there is no blur. On the other hand, when you do not see through hand fist, eyes’ lenses focus spread out and eye muscles squeeze to focus at different distances.

Pinholes use the same principle but they did not correct the vision full-time and limit the peripheral vision. Therefore, glasses and contact lenses were invented.
